Refer to the exhibit. According to the output, which parameter set is validated using the routing table of R7?

R7 has a gateway of last resort available as evidenced by the default route entry 'B* 0.0.0.0/0 via 10.6.25.2, 02:22:38'. R7 is receiving routes that were redistributed in EIGRP, indicated by route entries marked as 'D EX' with an administrative distance of 170. R7 will drop traffic destined to 10.90.8.0/24 because the route entry 'B 10.90.0.0/16 [200/0] via 0.0.0.0, 03:57:59, Null0' indicates that any traffic destined for this route will be sent to the Null0 interface, effectively discarding the traffic.
I think D is the best answer, however, I don't think the router would drop packets to 10.90.8.0/24, it would just send the packets out the gateway of last resort. Correct me if I am wrong please.
Router will "send" packets destined for 10.90.8.0/24 to Null0, so basically will drop that destination and not forward those packets
Null0 mean summary on that router
The route "10.90.0.0/16" is a summarized address range. And the "Null0" interface essentially means that any traffic destined for that route will be discarded by the router itself.
D EX = redistributed in EIGRP. We don't know for sure from what source these routes were redistributed.
missing gateway is wrong - therefore A/C - out B- is wrong because "R7 is receiving routes that were redistributed from BGP." REDISTRIBUTED FROM ?? BGP is the only Internet routing protocol and redistribution work for routing protocol in automous systems like EIGRP/RIP/OSPF
I Agree that the answer is D, small correction for the comment : BGP is not only internet routing protocol. It's ROUTING PROTOCOL. BGP has private AS# : 64512 to 65535
and the designation 'D EX' indicates an external route redistributed into EIGRP from another external source (routing instance or protocol).
- it has a default route: B* 0.0.0..... - It has routed redistributed into EIGRP, look at D EX, AD 170 - it'll drop packets: 10.90.0.0/16 via Null0
"D" is correct
Answer is D. Now move on.....
The router has only a BGP default gateway and 10.90.8.0/24 is a privat address. The router should drop the traffic.
ans is D
with a last resort never drop any frame
it´s D
how is it D if there is no gateway of last resort?
please can some explain why is the mean by R7 will drop traffic destined to 10.90.8.0/24 ?? from option D
